ATTORN EY Patented May 16, 1939 COKE OVEN DOOR Wilhelm Beimann, Bochum, Germany; Elizabeth Beimann, Bochum, Germany, administratrix of said Wilhelm Beimann, deceased, assignor, by mesne assignments, to the firm Otto-Wilputte Ovenbouw Maatschappij N. V., The Hague, Netherlands, a corporation of the Netherlands Application September 29, 1934, Serial No. 746,116

' In Germany January 5, 1933 12 Claims.

The present invention relates to coke ovens and particularly to coke ovens of the type comprising horizontally elongated open ended coking chambers arranged side by side with a flued heating wall between each adjacent pair of coking chambers. In such ovens each end of each coking chamber is normally closed by a door including an inner plug portion of refractory material extending into the coking chamber and an outer metallic portion which cooperates with a metallic door frame member surrounding the doorway and fixed in the oven brickwork to provide a packed or gas-tight joint between the door and door frame, the door and door frame members having 1| cooperating parts by which the door is releasably locked in its closed position. In such ovens vertically disposed metallic buckstays are provided at the ends of the heating walls to reinforce and armor the latter, and heretofore it has been customary to employ door frame members each having a portion at each side of the door way which is interposed between the brickwork at the end of the adjacent heating wall .and a buckstay in front of the latter so that the door frames are secured in place by the buckstays and cannot be removed without removing the buckstays.

The present invention has for its objects improvements in the construction and mounting of the door frame members, and in the relation to the buckstays of the door frame members whereby the latter may be readily removed for repairs or replacement, and for repairs to the brickwork at the ends of the heating walls, without removing or loosening either the buckstays at the ends of the heating wall or'the metallic flash plates which may be interposed between the heating wall ends and the buckstays, and whereby the door frame members may be made appreciably lighter in weight than the door frame members heretofore customarily employed in coke ovens of the above mentioned type.

In accordance with the present invention each door frame member is located between, and does not extend back of, the adjacent buckstays at op- 15 posite sides of the corresponding doorway, but is rigidly connected to said buckstays, or to parts in rigid engagement with the latter, by connecting means distributed along the entire height of the doorway and adjustable or detachable to permit .30 the removal of the door frame member without interfering with the general operation of the coke oven battery.

The various features of novelty which characterize my invention are pointed out with par- ,55 ticularity in the claims annexed to and forming a part of this specification. For a. betterun- Fig. 1, with the door in place in one and removed from the other of the two doorways shown;

Fig. 3 is a view similar to Fig. 1 showing a second embodiment of the invention;

Fig. 4 is a horizontal section generally similar to Fig. 2 and taken on the line 4-4 of Fig. 3;

Fig. 5 is a view generally similar to Fig. 1 illustrating a, third embodiment of the invention; and

Fig. 6 is a horizontal section on the line 6-45 of Fig. 5.

In the embodiment of the invention illustrated in Figs. 1 and 2, the refractory brickwork of the oven heating walls I is held together by U-shaped iron buckstays 2, there being two buckstays 2 in front of and bearing against each heating wall end. A metallic door frame 4 is provided for the reception of the door 8 removably closing each end of each of the horizontally elongated coking chambers 3 which alternate with the heating walls 1. Ordinarily and as shown, each door frame member 4 is in the form of a hollow rectangular frame, the sides of which are normally received in recesses Ir provided for the purpose at the adjacent corners of the adjacent heating walls, the sides of member 4 not projecting inwardly across the corresponding chamber 3. A packing is of asbestos or other suitable material shown as interposed between each door frame and the oven brickwork may be employed to insure a joint tight seal between the door frame and oven brickwork. As shown the door frames 4 are formed with lugs 4' which carry hooks 5 engaged by bolts or looking bars 9 secured to the outer metallic portion of the corresponding door 8. Each door 8 comprises an inner plug portion 8' of refractory material which in the closed position of the door extends into the corresponding coking chamber 3 as shown at the lefthand side of Fig. 2. As shown in Figs. 1 and 2, each door frame member 4 is formed with a machined surface 6 which in the closed position of the door is engaged by a joint sealing portion 1 of the door to form a gas tight seal of known type.

of each door frame member 4 engage outer surface portions of the door frame member and flrmly press the latter against the ends of the corresponding heating walls. As shown at the righthand sides of Figs. 1 and 2, wedges I2 between the ends of the bars I0 and adjacent portions of the door frame member 4 are used in lieu of the screws I I to secure the door frame member. As shown in Fig. 1, each side of each door frame is in operative engagementwith four bars III at suitably distributed distances along the length or vertical height of the door frame, and each of the bars II cooperating with the door frame at one side of each heating wall is alongside a corresponding bar in engagement with the other frame at the opposite side of the heating wall.

With the construction shown in Figs. 1 and 2,

i when it becomes desirable to remove a door frame 4, the corresponding screws II or wedges I! are removed, and the corresponding bars III are then moved longitudinally to clear the side edges of the door frame member which may then be withdrawn from its seal. Conveniently the door frame may be withdrawn with the corresponding door 8 locked in place therein by means of the usual door handling machine provided at the corresponding side of the battery to'move the doors into and out of place in the normal operation of the battery. The removal of the door frame members provided for not only permits door frame repairs or replacements but also facilitates repairs of the adjacent end portions of the heating walls. With the construction described, the removal of a door frame member I exposes enough of the adjacent heating wall endsto permit the chipping out of one or more of the heating wall bricks Ia, I b, Ic, Id, which in Fig. 2 are shown as forming the outer portion of each heating wall I, and the sides of the end heating wall flue Ie. As those skilled in the art understand, the end portions of the heating walls I ordinarily deteriorate more rapidly than the intermediate portions of the wall, and the facility provided by the present invention for access to the end portions of the heating walls for repairs without interfering with the general operation of the coke oven battery is an inherent and practically important advantage of the invention. Preparatory to the return of each door frame member which has been removed, new packing material Is if needed may be put in place.

In the embodiment of the present invention shown in Figs. 3 and 4, the door and door frame members 8A and IA respectively are similar in their general construction and disposition to door and door frame members of the construction shown in Figs. 1 and 2 described, but as shown the door frame members A are formed with side flanges l" which overlap metallic flash plates l6 interposed between the sides of the brickwork heating wall I and the corresponding buckstays I4. As shown in Figs. 3 and 4, there is a single buckstay II of I-beam form in front of each heating wall end. In the arrangement shown in Figs. 3 and 4, the means employed for securing the door frames 4A in 3 and 4, each door frame may be freed from the buckstays for removal, by the disconnection of the corresponding brackets I3, and the removal of a door frame facilitates door frame and heating wall repairs exactly as with the construction shown in Figs. 1 and 2.

The embodiment of the invention shown in Figs. 5 and 6 differs from that shown in Figs. 3 and 4 in respect-to the means employed for'anchoring the door frames in place. In Figs. 5 and 6, the door frame flanges 4 of the door frame members 43 are formed with bolt holes for the passage of bolts I8 by which the flanges 4 of each door frame are bolted to the adjacent flash plates IB. As shown the bolts I8 are stud bolts anchored in the flash plates, and the latter may be provided with reinforcing pads or nut portions I6 at their rear sides to improve the anchorage for the stud bolts I8. With the arrangement shown in Figs. 5 and 6, all that is required to free a door frame member for removal is the removal of the nuts I8 on the outer ends of the corresponding stud bolts.

This application is a continuation in part of my prior application, Serial No. 707,455 filed January 20, 1934.
